SBIG ST-8 Imager with CFW-8 Filter Wheel (Pre-owned)

Key features of the SBIG ST-8 Imager:

1. CCD Sensor: The ST-8 typically features a CCD sensor with a specific pixel resolution, pixel size, and dynamic range. The specifications may vary depending on the specific model and version.

2. Cooling System: CCD cameras for astrophotography often include a cooling system to reduce thermal noise during long exposure times. The ST-8 may have a Peltier cooling system to cool the CCD sensor.

3. Exposure Control: The camera allows for long exposure times, making it suitable for capturing faint astronomical objects. This is crucial for deep-sky astrophotography.

4. Connection Interface: The ST-8 likely interfaces with a computer using standard connections such as USB or serial ports.

5. Autoguiding Capability: Autoguiding is an essential feature for astrophotography. It allows the camera to make real-time adjustments to ensure precise tracking of celestial objects.

Key features of the CFW-8 Filter Wheel:

1. Filter Capacity: The CFW-8 is a filter wheel designed to hold multiple filters. It allows astronomers to quickly and easily switch between different filters during imaging sessions.

2. Filter Size: The wheel accommodates filters of a specific size. Common filter sizes for astronomical imaging include 1.25 inches and 2 inches.

3. Filter Changing Mechanism: The filter wheel features a rotating mechanism that allows users to select and position the desired filter in front of the CCD sensor.

4. Compatibility: The CFW-8 is likely designed to work seamlessly with the ST-8 Imager. It may be part of a complete imaging system offered by SBIG.
